Book excerpt: "Predictions of thermodynamic properties and phase equilibria in multicomponent systems are important to understand complex chemical reactions in high temperature processes. The CALPHAD (CALculation of PHAse Diagram) approach of thermodynamic calculations, nowadays, is considered one of the most efficient ways to understand complex chemical reactions and phase relations in multicomponent systems. Therefore, the development of adequate thermodynamic models and databases for materials of interest is essential. The goal of this study is to develop a new thermodynamic database for the ZrO2-containing unary, binary, and ternary systems in the CaO-MgO-Al2O3-SiO2-ZrO2 system, which is of great importance to understand the corrosion of ZrO2-based refractories in various pyrometallurgical industries. Due to the paucity of experimental data, experiments were conducted to verify the phase relations in the ZrO2-Al2O3 and ZrO2-CaO-SiO2 systems at 1873 K. Experimental results showed that the tetragonal zirconia solid solution can take up to 0.2 wt. % of Al2O3 at 1873 K. Moreover numerous liquidii were determined in the ZrO2-CaO-SiO2 system at 1873 K. All the thermodynamic property data and phase diagram data of the ZrO2¬-containing subsystems in the CaO-MgO-Al2O3-SiO2-ZrO2 system were critically evaluated and optimized in this study. The Gibbs energy of liquid oxide was described using the Modified Quasichemical Model (MQM) considering the short-range ordering of the molten oxide.The thermodynamic models of solid solutions were selected in consideration of real structural data. The prediction of high-order (>3) systems based on the optimizations of binary and ternary systems (≤3) shows good agreement with the experimental data available from the literature." --

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Phase diagram and thermodynamic properties of the K2O-Na2O-CaO-MgO-Al2O3-SiO2 system are important in various applications, such as glass/glass-ceramics, biomass combustion, steelmaking, refractory, and geology/mineralogy. In the present work, a critical evaluation and optimization of the phase diagram and thermodynamic properties of this six-component system was performed to develop an accurate thermodynamic database for industrial and academic research. Sub-binary/ternary systems containing K2O were thermodynamically optimized based on the critical assessment of all experimental data available in the literature, and a consistent set of model parameters of solid and liquid phases describing their Gibbs energies was obtained. Key phase diagram experiments were performed for the K2O-SiO2, K2O-Al2O3, and K2O-MgO systems in order to provide new phase diagram information and resolve the inconsistencies between existing experimental data. Equilibration/quenching experiments and thermal analyses were performed using K2O-containing samples sealed in Pt capsules to overcome the experimental difficulties (high hygroscopicity and volatile nature of K2O) and provide reliable results. In the study of the K2O-SiO2 system, the eutectic reaction, Liquid → K4SiO4 + K2SiO3, was successfully measured at 714 ± 6 °C. In the K2O-MgO system, the peritectic reaction of Liquid + MgO → K6MgO4 was determined to occur at 858 ± 14 °C. These two invariant reactions were determined for the first time. In the K2O-Al2O3 system, the thermal stability of K [beta]ʹʹ-alumina was confirmed up to 1600 °C from the present experiments, and a large discrepancy in the literature related to the eutectic temperature of Liquid → KAlO2 + [beta]-alumina was resolved.In the optimization of this study, the Modified Quasichemical Model (MQM) and Compound Energy Formalism (CEF) were used to describe the liquid and solid solutions, respectively, based on the structure of the solutions. In particular, solid solutions were modeled considering their lattice structure, in this way, a proper configurational entropy of the solution could be treated in the thermodynamic calculations. In the study of K2O-MgO-Al2O3 system, for example, a new solid solution model was developed to describe the details of ionic substitutions in non-stoichiometric K [beta]- and [beta]ʹʹ-alumina solutions. In both K2O-MgO-SiO2 and K2O-Al2O3-SiO2 melt, associates K2MgSiO4 and KAlO2 were considered, respectively, to describe the phase diagram, thermodynamic properties and structural data of liquid phase more accurately. With the model parameters optimized in binary and ternary systems, the phase diagram and thermodynamic properties of higher order systems in the K2O-Na2O-CaO-MgO-Al2O3-SiO2 system were well predicted. The database developed in this study is compatible with the FactSage thermodynamic databases and can be used for the prediction of any unexplored thermodynamic properties and phase diagram within the six-component system. Case studies of several industrial applications were also included at the end of this study." --

This book was released on 2011-04-12 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Temperature Metallurgical Processing contains the proceedings of the Second International Symposium on Thermal Processing of Minerals, Metals and Materials. This symposium explores physical and chemical transformations in materials that have been designed to facilitate the recovery of valuable metals or produce other useful materials. Representatives from both industry and academia focused on the latest innovative high temperature technologies. Because high temperature processes require high energy input, the presenters addressed the need for sustainable technologies that could provide low energy consumption and low pollution emissions. The symposium also examined the thermodynamics and kinetics of chemical reactions, phase transformations at elevated temperatures, and characterization of materials used or produced in high temperature processing.

Available in PDF, EPUB and Kindle. Book excerpt: Metal oxide-zirconia systems are a potential class of materials for use as structural materials at temperatures above 1900 K. These materials must have no destructive phase changes and low vapor pressures. Both alkaline earth oxide (MgO, CaO, SrO, and BaO)-zirconia and some rare earth oxide (Y2O3, Sc2O3, La2O3, CeO2, Sm2O3, Gd2O3, Yb2O3, Dy2O3, Ho2O3, and Er2O3)-zirconia system are examined. For each system, the phase diagram is discussed and the vapor pressure for each vapor specie is calculated via a free energy minimization procedure. The available thermodynamic literature on each system is also surveyed. Some of the systems look promising for high temperature structural materials.
